#1: for this question can you help me in part a and b I don't know how to answer them in complete sentence.

-x2 + 1 h(x ) = Let f (x) = x4 + 4x3 - 2x2-12x + 9, 9(X)= vx-+2x-3 and X2 + 2x- 3 Part A: Use complete sentences to compare the domain and range of the polynomial function f (x) to that of the radical function g(x). (5 points) Part B: How do the breaks in the domain of h (x) relate to the zeros of f (x)? (5 points)Let f (x) be a polynomial function with a zero of multiplicity of 1 at 3 and a zero of multiplicity of 2 at 1. Let g(x) be the radical function 9(x) - x - 3. Part A: Using the Factor Theorem, determine the polynomial function f (x) in expanded form. Show all necessary calculations. (5 points) [f(x) if x
